1、部署分离的LAMP，部署到二台服务器上，php加载xcache模块
1)在c2服务器安装httpd, php, php-mysql
[root@c2 ~]# yum install httpd php php-mysql -y2)在mariadb服务器安装数据库 mariadb-server
[root@mariadb ~]# yum install mariadb-server -y3)启动服务
[root@c2 ~]# systemctl start httpd
[root@mariadb ~]# systemctl start mariadb.service4）测试
[root@c2 html]# ll -lh
total 3.6M
-rw-r--r-- 1 root root 16 May 14 20:43 index.html
-rw-r--r-- 1 root root 3.6M May 10 21:45 npp
[root@c2 html]# pwd
/var/www/html在c1安装httpd-tools才能使用ab命令
[root@c1 ~]# yum install httpd-tools-2.4.6-93.el7.centos.x86_64 -y
[root@c1 ~]# ab -c10 -n 100 http://c1/npp

a.编译安装
[root@c2 html]# yum -y install php-develb.官网下载xcache-3.2.0.tar.bz2；上传到/usr/local/src/目录并解压缩
[root@c2 src]# tar -xvf xcache-3.2.0.tar.gzc.用命令phpize 生成预编译脚本
[root@c2 xcache-3.2.0]# phpize
Configuring for:
PHP Api Version: 20100412
Zend Module Api No: 20100525
Zend Extension Api No: 220100525
[root@c2 xcache-3.2.0]# ll configure
-rwxr-xr-x 1 root root 414469 May 14 21:00 configured.预编译
[root@c2 src]# cd xcache-3.2.0/
[root@c2 xcache-3.2.0]# ./configure --enable-xcache e.编译和安装
[root@c2 xcache-3.2.0]# make -j 4 && make install[root@c2 xcache-3.2.0]# ls /usr/lib64/php/modules/
curl.so mysqli.so pdo.so sqlite3.so
fileinfo.so mysql.so pdo_sqlite.so xcache.so
json.so pdo_mysql.so phar.so zip.so
f.加载xcache模块并重启httpd服务
[root@c2 xcache-3.2.0]# cp xcache.ini /etc/php.d/
[root@c2 xcache-3.2.0]# ls /etc/php.d/
curl.ini mysqli.ini pdo_mysql.ini sqlite3.ini
fileinfo.ini mysql.ini pdo_sqlite.ini xcache.ini
json.ini pdo.ini phar.ini zip.ini[root@c2 xcache-3.2.0]# systemctl restart httpd.serviceg.测试
[root@c1 ~]# ab -c10 -n 100 http://c2/npp

2.1 在第1小节的lamp基础上实现此场景。
2.2 在数据库服务器新建wpdb库和wpuser远程连接用户
[root@mariadb ~]# mysql
Welcome to the MariaDB monitor. Commands end with ; or g.
Your MariaDB connection id is 2
Server version: 5.5.65-MariaDB MariaDB Server
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type ‘help;‘ or ‘h‘ for help. Type ‘c‘ to clear the current input statement.
MariaDB [(none)]> create database wpdb;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> grant all privileges on wpdb.* to wpuser@‘%‘ identified by "wppass";
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)###测试远程连接数据库
[root@c2 ~]# mysql -uwpuser -pwppass -hc3
Welcome to the MariaDB monitor. Commands end with ; or g.
Your MariaDB connection id is 3
Server version: 5.5.65-MariaDB MariaDB Server
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type ‘help;‘ or ‘h‘ for help. Type ‘c‘ to clear the current input statement.
MariaDB [(none)]> 2.3 官网下载并解压缩WordPress博客程序到网页站点目录下
[root@c2 html]# ls
wordpress wordpress-5.0.3.tar.gz
[root@c2 html]# pwd
/var/www/html2.4 设置wordpress目录权限
[root@c2 html]# setfacl -R -m u:apache:rwx wordpress2.5 打开http://c3/wordpress进行页面安装
3、收集apache访问日志，并实现图形化展示。
3.1 rsyslog收集apache访问日志
3.1.1 修改apache配置文件
[root@c2 ~]# vim /etc/httpd/conf/httpd.conf
#CustomLog "logs/access_log" combined
CustomLog "|/usr/bin/logger -p local6.info" combined3.1.2 修改rsyslog的配置文件
[root@c2 ~]# vim /etc/rsyslog.conf
local6.* /var/log/apache_access_log3.1.3 重启rsyslog和apache服务
[root@c2 ~]# systemctl restart rsyslog.service httpd.service3.2 rsyslog将日志记录于MySQL中
3.2.1 在mysql server上授权rsyslog能连接至数据库服务器
[root@mariadb ~]# mysql
Welcome to the MariaDB monitor. Commands end with ; or g.
Your MariaDB connection id is 59
Server version: 5.5.65-MariaDB MariaDB Server
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type ‘help;‘ or ‘h‘ for help. Type ‘c‘ to clear the current input statement.
MariaDB [(none)]> grant all on Syslog.* to ‘apache‘@‘%‘ identified by ‘centos‘;
Query OK, 0 rows affected (0.01 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)3.2.2 在rsyslog服务器上安装mysql模块相关的程序包
[root@c2 ~]# yum install rsyslog-mysql -y3.2.3 为rsyslog创建数据库及表
[root@c2 ~]# mysql -uapache -pcentos -h c3 < /usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql[root@c2 ~]# mysql -uapache -pcentos -h c3 -e "show databases;"
+--------------------+
| Database |
+--------------------+
| information_schema |
| Syslog |
| test |
+--------------------+3.2.4 配置rsyslog将日志保存到mysql中
[root@c2 ~]# vim /etc/rsyslog.conf
local6.* :ommysql:10.0.1.244,Syslog,apache,centos
3.2.5 重启rsyslogd服务
[root@c2 ~]# systemctl restart rsyslog.service3.2.6 验证数据库是否有日志记录
MariaDB [(none)]> select * from Syslog.SystemEvents order by DeviceReportedTime DESC limit 1G

3.3.1 在rsyslog服务器上安装绘图工具php-gd
[root@c2 ~]# yum install php-gd -y3.3.2 安装LogAnalyzer
[root@c2 html]# tar xvf loganalyzer-4.1.5.tar.gz
[root@c2 html]# mv loganalyzer-4.1.5 log
[root@c2 html]# cd loganalyzer/
[root@c2 loganalyzer]# touch config.php
[root@c2 loganalyzer]# chmod 666 config.php3.3.3 配置loganalyzer
[root@c2 html]# setfacl -Rm u:apache:rwx loganalyzer
[root@c2 loganalyzer]# systemctl restart httpd.service 在浏览器地址栏输入：http://10.0.1.243/log
点击src
3.3.4 安全加强
[root@c2]#cd /var/www/html/loganalyzer
[root@c2]#chmod 644 config.php以上是关于实现lamp架构及统一日志管理的主要内容，如果未能解决你的问题，请参考以下文章
